从Python3.10升级到python3.11后Joblib出错

Question

从python3.10更新到python3.11后，一个简单的命令如下：

joblib.load("test.pkl")

因错误而失败

TypeError: '>' not supported between instances of 'NoneType' and 'sys.version_info'

完整错误：

尝试将 joblib 更新到最新版本（1.4.0），但这并没有解决问题。 （如果与任何方面相关的话，这是在 Ubuntu 上）

你必须更新 Pasty 本身。旧版本的 Pasty 与 python 3.11 不兼容。
